用于DDR3访存优化的数据缓冲机制

为提高DDR3控制器访存效率,设计了基于DDR3存储器预取访问数据长度的数据缓冲机制,将访存请求分为三种基本类型并分别排队处理,降低数据丢弃和实际动态随机访问存储器访问发生次数。针对图像和视频类应用程序的实验结果表明,相对于传统先到先服务的DDR3访存控制器,该机制取得了平均21.3%、最好51.3%的性能提升,硬件开销在可接受范围内。     

Low-intensity conflict in Eastern Sudan: A comparative approach to the development of rebel groups

This article discusses the development of a low-intensity conflict in Sudan's eastern region between 1994 and 2006. Drawing on data collected in the region in 2009, recruitment processes within three different insurgent groups are analysed and compared, paying attention to the impact of these processes on insurgents' organisational development and military capacity. The peace process in Eastern Sudan is further discussed, focusing specifically on the disarmament, demobilisation, and reintegration (DDR) programmes for former insurgents. The article finally discusses current developments and draws conclusions regarding the risk of renewed rebellion in Eastern Sudan.     

The disconnect between arms control and DDR in peace processes

The article discusses the disconnect between arms control and disarmament practices vis-à-vis peacebuilding practices. It critically analyzes Disarmament, Demobilization, and Reintegration (DDR) practices focusing on their absence of dialogue with international arms control and disarmament (ACD) practices. It proposes that a conversation between experts involved in these distinct practices could promote a political discussion on the place of weapons held by state and non-state actors in times of peace. The argument is illustrated through an analysis of the treatment of rules on weapons in the Colombian peace process (2012–present) with the Revolutionary Armed Forces of Colombia (FARC). The article concludes that the disconnect between the arms control and disarmament and the peacebuilding associations, as seen in the context of DDR practices, reinstates the rule on the monopoly of violence by the state, preventing a broader discussion of the role of weapons and violence in the building of political communities.     

Network structure of insurgent groups and the success of DDR processes in Colombia

We argue that organizational structure of insurgent organizations influences the prospects for success in a disarmament, demobilization, and reintegration process (DDR). In essence, we argue that more cohesive, tighter networks have higher levels of supervision and control on its military units and increase the probability of successful DDR processes. In order to evaluate our hypotheses, we use the theory of networks to map and characterize the network structure of the United Self-Defense Forces of Colombia (AUC) and the Revolutionary Armed Forces of Colombia (FARC). Our results suggest that armed military units grouped in smaller and more isolated components on the network remilitarize with higher probability with respect to other units on the network. Also, we find that military units with high degree of centrality on the network play an important role for the risk of conflict recurrence and success in a DDR process.
